Which command applies changes to the infrastructure as specified in the Terraform configuration files?

The command that applies changes to the infrastructure as specified in the Terraform configuration files is "terraform apply." This command reads the configuration files to determine the desired state of the infrastructure and then interacts with the provider APIs to make the necessary changes to achieve that state. During this process, Terraform will carry out tasks such as creating, updating, or deleting resources to align the real-world infrastructure with the specifications outlined in the Terraform files.

"Terraform apply" also provides a crucial safety check, as it typically shows a preview of the changes that will be made before actually applying them, allowing users to review and confirm these changes. This step is fundamental in Infrastructure as Code practices, where understanding the implications of changes is essential for maintaining stable and reliable infrastructure.

The other options do not represent valid Terraform commands. For example, "terraform push" is not a valid command in Terraform's command set, as Terraform synchronizes the state through its state file rather than a push mechanism. "Terraform create" does not exist, as Terraform manages resources differently by defining their configuration and applying changes rather than using a command that implies a direct creation action. Similarly, "terraform deploy" is not recognized as an appropriate Terraform command, and while it may seem like a logical choice, it
